The Road to Serfdom

by Friedrich A. Hayek

There are, finally, undoubted fields where no legal arrangements can create the main condition on which the usefulness of the system of competition and private property depends: namely, that the owner benefits from all the useful services rendered by his property and suffers for all the damages caused to others by its use. Where, for example, it is impracticable to make the enjoyment of certain services dependent on the payment of a price, competition will not produce the services; and the price system becomes similarly ineffective when the damage caused to others by certain uses of property cannot be effectively charged to the owner of that property. In all these instances there is a divergence between the items which enter into private calculation and those which affect social welfare; and, whenever this divergence becomes important, some method other than competition may have to be found to supply the services in question.
